2. FORECAST (01 JUNE - 07 JUNE)
Solar: Low

Geomagnetic:  Mostly quiet to unsettled with possible active periods
	      later in the forecast period.

Frequencies: Mostly near predicted monthly values to depressed 15%
             at times. No SWFs.

PEASE NOTE: 
At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
